ADUM240E0WBRWZ

Overview

The ADUM240E0WBRWZ is a quad-channel digital isolator utilizing iCoupler magnetic coupling technology. It provides robust isolation with a rated insulation voltage of 5000 Vrms and a common-mode transient immunity of 75 kV/µs. The device supports data rates up to 150 Mb/s with a propagation delay of approximately 7.2 ns. It operates within a supply voltage range of 2.7 V to 5.5 V, drawing typical quiescent currents of 8.6 mA on the driver side and 2.6 mA on the receiver side. The component is housed in a 16-lead SOIC package and is qualified under AEC-Q100 standards for automotive applications.

Feature Summary

• Integrates four independent digital isolation channels using proprietary iCoupler magnetic coupling technology
• Provides high common-mode transient immunity of 75 kV/µs for reliable signal transmission in noisy environments
• Supports unidirectional data transmission with configurable channel directions
• Meets AEC-Q100 qualification requirements for automotive electronic systems

Applications

• Automotive engine control units requiring isolated communication interfaces
• Industrial motor drives with high-voltage isolation needs
• Medical equipment requiring reinforced safety isolation
• Power conversion systems with galvanic isolation requirements

Procurement Notes

Verify availability status as this part may have restricted supply or limited production runs. Confirm the specific suffix matches the required configuration. Check for alternative packages if lead times are excessive. Ensure compliance with RoHS directives before procurement. Validate that the AEC-Q100 qualification meets your specific automotive grade requirements.

Selection Notes

Select this component when four isolated channels are required in a single package. Consider the 150 Mb/s data rate for high-speed applications. Evaluate the 5000 Vrms insulation rating against system voltage requirements. Compare power consumption with other isolators if battery operation is critical. Verify temperature range compatibility with the intended operating environment.

Part Context

This device belongs to the ADuM240E family of quad-channel digital isolators from Analog Devices. It shares the same core iCoupler technology as related models but offers specific channel configurations and performance characteristics. The family includes variants with different channel directions and speed ratings to suit various isolation applications.

Replacement Considerations

Direct substitutes include ADUM240E1WBRWZ and ADUM240E2WBRWZ, which offer different channel direction configurations. Cross-reference pinouts and electrical specifications carefully when substituting. Verify that the replacement maintains the required insulation voltage and CMTI ratings.
